Unable to clone Bitbucket repos using Sourcetree v3.4.17

[Derek Fritz]

IT migrated my laptop to a new domain, and I'm now unable to clone Bitbucket repos via Sourcetree v3.4.17. My settings are as follows:

     Hosting Service: Bitbucket
     Host URL: https://bitbucket.org
     Protocol: HTTPS
     Authentication: OAuth
     Authentication OK

I'm also using System Git v2.44.0.

With "Disable SSL certificate validation" unchecked, I get the following error:

     Error: fatal: unable to access 'repo name': SSL certificate problem: unable to get local issuer certificate

If I uncheck "Disable SSL certificate validation" (I realize this may be unsafe), then I get the following:

     Error: remote: Invalid credentials fatal: Authentication failed for 'repo name'

I also get this error if I switch from System Git to Embedded Git.

My coworker has identical settings and isn't having this issue, although he hasn't been migrated to the new domain yet.

Any help or suggestions would be appreciated.

It really depends on how you are authenticating.  Have you tried updating the credentials?  are you using PAT?  If you are using PAT you will need to regenerate.
